[#144] Use reserve token for royalty decimals/symbol

[realproject7]

Fixes royalty formatting to use reserve token (via tokenBond()) instead of storyline token for decimals() and symbol(). Applied to both claim.ts and status.ts. Also exports mcv2BondAbi from SDK. Fixes #144

T2b Review: APPROVE

Correctly reads decimals()/symbol() from the reserve token via tokenBond() instead of the storyline token, in both claim.ts and status.ts. SDK re-exports mcv2BondAbi cleanly.

Non-blocking note: (bond as readonly unknown[])[4] as Address is fragile — a comment noting which struct field index 4 represents (e.g., // reserveToken is 5th field in BondParams struct) would improve readability. Could also consider adding a typed getReserveToken() helper to the SDK in a follow-up.
